What fertilizer does elm apply?

During the growth period from April to June (except rainy days), apply thin organic fertilizer or cake fertilizer every 15- 10 days. Nitrogen, phosphorus and potassium are used together, and urea is sprayed on the leaves about 2 days after pruning. In winter 10 days, organic fertilizer or cake fertilizer water mainly composed of phosphorus and potassium fertilizer is poured once before entering the house, and cake fertilizer tablets are applied once after entering the house.

Elm doesn't like big fertilizer. It is only applied once in early spring and early autumn, and it doesn't need to be applied more, and the concentration is low. The fertilizer can be decomposed cake fertilizer water, combined with nitrogen, phosphorus and potassium compound fertilizer to ensure sufficient nutrients, so as to grow better.

In addition, autumn is also the peak of growth, which will consume a lot of nutrients and should be supplemented in time. It can also increase the cold resistance and is beneficial to winter.

Extended data:

Elms love light, and only in sunny places can they grow healthily and well. If the light is insufficient, its growth is slow, its branches are fine, its leaf spacing is long, its leaves are light, and its fibrous roots are few and thin. So there must be enough light.

Summer is the golden period for Ulmus pumila to take root. Enhanced light will promote its vigorous life activities, accelerate photosynthesis and metabolism, and make the roots strong. Generally, there is no sunshine in the family garden from morning till night, so there is no need to shade it.

Where the roof platform has a long illumination time, as long as the water supply is timely, it will not harm the elm. The growth of elm roots depends entirely on whether there is enough light.
